JBL Professional VERTEC Line Array Calculator II

VERTEC System software

What is it?V1.1 of JBL’s control software for VERTEC system users.
DetailsSaid to offer simulation of mixed-model arrays from the entire range of VERTEC enclosures, the V 1.1 upgrade includes a range of new features while retaining much of the appearance and functionality of the original V1.0 version. For example, new VERTEC subcompact line array accessories – VT4886-SF, VT4886-DF88 and VT4886-DF89 – are included and parametric EQ (compatible with JBL DrivePack, Crown Audio I-Tech/I-Tech HD and dbx 4800) has been introduced. The software now links signal delay functions for all VT4889, VT4888, VT4887A, VT4887 and VT4886 enclosures – including DrivePack models – while subwoofer model delays remain individually selectable. LAC II V1.1 also features an SPL Mapping View probe (displaying XY coordinates and SPL) and it is now possible to manually create circuit groups so that EQ, delay and gain are linked. A new user-selectable Auto-Update function has been introduced (a check for updates can be launched from the Help menu) and VERTEC V4 preset data is now included in the Frequency Range menu. As with the previous version, V1.1 features enhanced acoustical modelling with colourised graphical representation of results, including SPL mapping, 0 dB Isobar, and SPL attenuation modes. Line Array Calculator II V 1.1 is available for download from the company’s website.
